Please explain what exactly is the problem with installing dependencies on demand compared to an 'npm install -g bla', 'brew install bla' or 'apt install bla'? It requires exactly the same amount of trust and is the the same thing under the hood, just that it happens automatically on first invocation of a script.

Then put shell function to your globals which will mimic install + run. It’s literally like 5 minutes of work max and you’ve spent way more arguing over it already.

Nobody says Deno is not better overall than Node. It clearly is, across the board. And nobody cares.

If Deno would provide actual improvements people would care about then for sure it would survive. The problem is that it didn’t. It was just fun project and creators learned a lot for sure. And entire js ecosystem improved thanks to Deno’s push.
